To establish a method used for optimization of harvesting time and determine the best time for harvesting Rumex gmelini.
An HPLC method was applied to determinate the contents of seven active constituents(resveratrol, polydatin, chrysophanol 1-glucoside, nepodin, emodin, chrysophanol and physcion)of R. gmelini at different development stage. The result was analyzed by principal component analysis.
The accumulation of active constituents showed a regular pattern.
The best harvesting time of R. gmelini is early July.
建立一种用于优化采收时间的方法，并确定皱叶酸模的最佳采收时间。
采用高效液相色谱法测定皱叶酸模在不同发育阶段七种活性成分（白藜芦醇、虎杖苷、大黄酚-1-葡萄糖苷、尼泊尔黄酮、大黄素、大黄酚和大黄素甲醚）的含量。结果通过主成分分析进行分析。
活性成分的积累呈现出规律模式。
皱叶酸模的最佳采收时间为7月初。
